The current algorithm doesn't take into account that roads with
access=private or which have barriers on them with access private
should be passed through, by default:


And, as Maarten said, the Permalink is not precise enough, it should
provide 5 decimals to be effective in locating a point.

Another problem is that the default shortest route for cars should
probably avoid tracks, or a "shortest on paved roads" algorithm should
be provided.

Problem visible here:

Also, the fast and short route could be the same if the difference
isn't noticiable like above, where both the fast and the short route
are allegedly 4.7km long.
